pytest-mongo 1.1.0

MongoDB process and client fixtures plugin for py.test.

pytest-mongo

Package status

What is this?

This is a pytest plugin, that enables you to test your code that relies on a running MongoDB database. It allows you to specify fixtures for MongoDB process and client.

How to use

Plugin contains two fixtures

• mongodb - it’s a client fixture that has functional scope, and which cleans MongoDB at the end of each test.

• mongo_proc - session scoped fixture, that starts MongoDB instance at the first use and stops at the end of the tests.

Simply include one of these fixtures into your tests fixture list.

You can also create additional MongoDB client and process fixtures if you’d need to:

from pytest_mongo import factories

mongo_my_proc = factories.mongo_proc(
    port=None, logsdir='/tmp')
mongo_my = factories.mongodb('mongo_my_proc')

Note

Each MongoDB process fixture can be configured in a different way than the others through the fixture factory arguments.

Configuration

You can define your settings in three ways, it’s fixture factory argument, command line option and pytest.ini configuration option. You can pick which you prefer, but remember that these settings are handled in the following order:

• Fixture factory argument

• Command line option

• Configuration option in your pytest.ini file

What	Fixture factory argument	Command line option	pytest.ini option	Default
Path to mongodb exec	executable	–mongo-exec	mongo_exec	/usr/bin/mongod
MongoDB host	host	–mongo-host	mongo_host	127.0.0.1
MongoDB port	port	–mongo-port	mongo_port	random
Path to store logs	logsdir	–mongo-logsdir	mongo_logsdir	$TMPDIR
Additional parameters	params	–mongo-params	mongo_params

Example usage:

• pass it as an argument in your own fixture

  mongo_proc = factories.mongo_proc(port=8888)

• use --mongo-port command line option when you run your tests

  py.test tests --mongo-port=8888

• specify your directory as mongo_port in your pytest.ini file.

  To do so, put a line like the following under the [pytest] section of your pytest.ini:

  [pytest]
  mongo_port = 8888
